Justification:
Although there are few data regarding this species, it is listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a several protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

This species occurs in Songshan, Shennongjia, and Pangquangou Nature Reserves (CSIS 2008), and may be present in other protected areas. Research is needed in the areas of population status, biology and ecology, habitat status, and threats. In China, this species was regionally Red Listed (as M. mystacinus) as Near Threatened nearly meeting the criteria for listing as Vulnerable under criterion A1bc (Wang and Xie 2004).
